2014 – Data Presentation in the 21st Century: Giving Complex Surveillance Data Intuitive Meaning

Lyndon Johnson and Jamie Campbell

Data presentation is an important and much discussed aspect of Dam and asset safety worldwide. We rely on drawings and graphs of instrumentation data to tell us things about our assets that are hidden from the eye and to monitor changes linked to failure modes. It’s common that we look at data gaps for our assets, data quality and data processing but how often do we rethink the fundamentals of data presentation?

Engineers and data analysts, as humans, have evolved in a 3D world with our senses to match match. According to Keller GB, et al (2012) almost 20% of the human brain is dedicated to processing vision with up to 60% involved when locating, scaling and referencing objects in 3D space. As a result, 3D is an extremely efficient platform from which to display and disseminate information.

This paper discusses methods to efficiently transfer asset information into 3D and how to present animated surveillance data against asset models. The paper discusses how these methods work, benefits and limitations in the context of modern dam asset portfolio management and presents some key case studies of where and how these methods have assisted with asset diagnoses.
